Describe three type of Decomposition Reaction |
|
Answer» Types of decomposition reactionLet us look at the three main types of decomposition reactions which we see around us.\t\tThermal decomposition reaction A thermal decomposition reaction can be defined as a decomposition reaction which is activated by thermal energy. The reaction is generally endothermic as energy is required to break chemical bond in order to separate the constituent elements. example of thermal decomposition reaction CaCO3 → CaO + CO2 When heated Calcium Carbonate,decomposes into Calcium Oxide and Carbon Dioxide. This process is employed in the manufacturing of quick lime which is an important component in industries.\t\t\tElectrolytic decomposition reaction\t\tAn electrolytic decomposition reaction is a type of decomposition reaction in which the activation energy for decomposition. Example of electrolytic decomposition reaction Dissociation of water:2H2O→ 2H2 + O2\t\t\tPhoto decomposition/ photolytic decomposition/ photochemical decomposition \t\tA photo decomposition is the type of decomposition reaction in which the reactant is broken down to its constituents by photons.Example of photo decomposition reaction O3 + hν → O2 + O(1D)Photolysis occurs in the atmosphere wherein ozone molecules is broken down into oxygen molecule and atomic oxygen.\t\t Light, electrolisis and thermal decomposition reaction |
